The movie is about a woman who used to be fat in high school gets rejected by her crush. The movie takes place in a skyscraper several years after high school downtown for a reunion I believe. the woman acts like a victim but turns out to be the killer, and kills everyone one by one. I think she is a celebrity chef and the very last scene of the movie she slits her crush’s throat and puts an apple in his mouth, and all the other former classmates are made up like a thanksgiving dinner. All of it was revenge for everyone calling her fat in high school.
